RDF (and concepts) has no retrieval action in the current round of
specifications - it is defining a language, with no processing model.

We have noted appendix C.2 of RDF M&S after you pointed it out:
 [[An RDF processor can expect to use the schema URI to access the
 schema content]]
 -- http://www.w3.org/TR/1999/REC-rdf-syntax-19990222/

which does somewhat refer to retrieval but only obliquely.  It does
not require that the access to the schema content is found by
retrieval.  As far as I udnerstand, what URIs or URI namespaces
resolve too is not part of RDF.

URI-refs in RDF do not require documents to exist (bits to be
returned when the URIs are resolved).  URI-refs in general do not
require this either.
